Application filed February 26, 1917. Serial No. 150,974.

To all whom it may concern:

Be it known that I, EDGAR Gr. Bnrnnnenn,

' a citizen of the United States, and a resident of Atlanta, in thecounty of Fulton. and State of Georgia, have invented anew and Improved Heater, of which the following is a full, clear, and exact description.

' the purpose of keeping the engines warm the well known manner.

during the winter months. I 7

An bject of the invention is to provide a safe and inexpensive heater which will supply suficient heat for the'engine under the hoodwithout the risk of an explosion ghati1 may be caused by gas leaks under the o0 With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views. 1

Figure 1 is a perspective view of a heater embodying myinvention, certain parts of which are broken away to illustrate the details of construction;

Fig. 2 is a vertical cross section; and

Fig. 3 is a perspective view of the inner screen provided with a water-circulating tube.

Referring to the drawings, 5 is a burner of the type used with a'solene torches when gasolene is used as a el for the lamp. If other fuel is used, a suitable burner for such fuel will be rovided in place of the burner 5. A pilot light 6 is provided near the cup 7 of the-burner, the pilot light being supplied with fuel from the main conduit 8 from a point beyond a-valve 9 which controls the supply to the burner. The conduit 8 is connected to the gasolene supply of the automobile. A; suitable sparking arrangement 10 is provided in proximity of the pilot light and cup to ignite the fuel thereat and preheat the burner to asify the fuel in he valve 9 is o erable from the seat of the operator of t e vehicle. 1

- The burner 5 is mounted centrally on the base 11, preferably of rectanar contour.

The base 11 carries. a cone 12 of meshed fabric which incloses the burner. The cone is inturn inclosed in a pair of spaced cups 13 of meshed fabric and preferably of rectangular cross section in either plane. The two cups are also supported on the base 11, the open ends of the cups and cone being engaged by flanges raised'from the base, so as to prevent any movement of said cups and cone on the base.

The outer cupis surrounded by a cross brace 15, the ends of which are secured to the base. Preferably the ends 16 of said cross brace are made to support the flanges 14:, so that when the brace is removed from the base 11, the cups and the cone are removed therewith. The base 11 circumscribed by the cone 12 is dished as shown at 17, and is provided with a central opening 18 through which a portion of the burner 5 7 projects. This opening serves also as. an escape for the fuel that condenses within the 'cone or that overflows from the cup. The

opening 18 is screened by metal fabric 19. The burner below the base is provided with a valve 20 whereby the size of flame and, therefore, the quantity of heat generated may be controlled. The means for securing the burner at any desired position may be provided at the base or on the brace, depending on the size of the burner and the place it is desired to have itvsecured under the engine hood of a motor vehicle' In places where the temperature is very low, the water that circulates through the englne may be caused to circulate about the cone 12, so as to bepartially preheated thereat. In such cases a water conduit 21 will be wound about the outer surface of the meshed cone 12' in a manner as shown in Fig. 3.

By providing three successive metal gauzes about the burner, any danger of an explosion is obviated, for the temperature at the outer gauze will be below the ignition temperature of most of the gases that may find their way under the hoodof an engine.

The securing of all the gauzes to the cross I brace results in a unitary structure which permits the removal of the superstructure of the heater in a unit and thereby affords quickaccess to the burner.

Iv claim 1. A heater of the class described comigniting the burner, a plurality of interengaging metal-gauze members surmounting the burner, and a cross brace adapted to encompass the outer gauze member and adapted to be securedto the base, said cross brace having means for interengaging all of said gauze members whereby the gauze members are rembvable with the cross brace.

metal-gauze members whereby the metal mamas gauze members are removable with the I brace. I

3. A heater of the class described comprising a base having a central depressed part, a burner on said base in the central depressed part, a metal-gauze, coneshaped member resting on the base and inelosing the burner, a; pair of interengaging cups of metal gauze engaging the base and inclosing the cone-shaped metal-gauze member, and a cross brace having flanges for engag- .ing the cup-shaped and the" cone-shaped members, said cross brace having means for engaging the base whereby all of said metaigauze members are secured to the base when the cross brace is secured to the base.
